Self compacting concrete with recycled aggregate A USE OF CONTAMINATED RECYCLED AGGREGATES FOR CONCRETE

The broad use of recycled aggregate in concrete is hindered by its higher water absorption two to three times that of normal aggregate and the increased shrinkage of the resulting recycled aggregate concrete These drawbacks result largely from the old mortar/cement paste adhered to the surface of recycled aggregates as shown schematically in Fig 1 Therefore the purpose of this study is recycled aggregates in the mix design of concrete is a solution to decrease nature depletion Natural Natural concrete slabs were cured in water sea water chloride solutions or sulphate solutions and then
